摘要
通过试验 ,详细地分析了钢骨轻骨料混凝土简支梁的混凝土裂缝发展规律、混凝土及钢骨的受力特性 ,研究梁的抗剪机理及其破坏模式 ,确定影响钢骨轻骨料混凝土梁抗剪强度的主要因素 ,利用强度叠加理论得到钢骨轻骨料混凝土简支梁的抗剪承载力计算公式 ,理论计算结果与试验结果吻合良好。
The pattern of crack propagation and the forced f eatures of concrete and section steel are analyzed in detail by the experiment o f the steel encased light aggregate concrete beams.The failure mode and shear me chanism have been researched.The influence factors on the ultimate shear strengt h is determined by the theory and experiment.The theoretical calculating formula s of shear strength of steel encased light aggregate beams are proposed by compl ex method.The formulas are verified by testing results.A good agreement is obtai ned between the calculating results and the experimental results.
